Coating & Surface Treatment Options

  • Plating

    Plating is a manufacturing process where a thin coating is applied to a component’s surface through chemicals or electric current (electroplating). Most commonly used plating types for springs are Zinc, Nickel, Cadmium, Black Oxide, Powder Coat, Gold, Silver & Dry Film Lube.

  • Passivation

    Passivation is a chemical treatment used in engineering to manipulate the material, causing it to become more “passive” or less affected by environmental factors like corrosion. In this process, an acidic substance is added to the part’s surface to remove iron deposits and add a protective layer to guard against possible chemical reactions with the surrounding air.

  • Dyeing

    Dyeing is generally used to increase accuracy by helping assembly line workers identify specific parts.
